Move service-destroy HTML into the footer.
Merge pull request #365 from kadams54/inspector-footer

This ticket moves the link into the footer for the service inspector. This change is consistent with the ghost inspector, which already has the same link in the footer.

### QA

1. Drag a charm to the canvas and deploy it.
2. Drag a second charm to the canvas, but don't deploy it.
3. Click on the deployed service and verify that the "Destroy Service" link is anchored to the bottom of the inspector (expand some of the unit info so that you activate scrolling).
4. Click on the ghost service and verify that the location and appearance of this link is consistent between the two different types of inspectors.
5. Verify that the link and icon work as expected in both types of inspectors.
Fix rendering of the left-breakout slot.

QA: Ensure viewing a charm works. Deploy a charm - ensure that the unit detail view works (it should have a status set to something, rather than blank), and ensure that viewing the charm details for a deployed service works.
Correctly add and remove machine and container tokens including their committed state.
Merge pull request #367 from huwshimi/update-tokens

This branch adds and removes container tokens and sets the committed states on tokens.

QA:
- drag two services to the canvas
- open the machine view
- drag one of the unplaced units to "Create new machine"
- a machine "new0" should have been created and should have a blue background
- click on "new0" and the bare metal container should be visible in the container column
- drag the second unplaced unit to "Create new container"
- a new container "new0/lxc/new1" should have been created with a blue backround
- click "deploy" and then "confirm"
- the "new0" machine should be removed and replaced with a new machine "0" without the blue background
- the "new0/lxc/new1" contaier should be removed and replaced with a new container "0/xc/o" without the blue background
